Protection & Control Engineering Services
We provide full-spectrum engineering for substation protection schemes, generating systems, and industrial plant distribution networks. Our designs safeguard expensive high-voltage equipment (transformers, generators, busbars, lines) while optimizing selectivity to isolate electrical faults instantly.
Protection Panel Engineering
Designing protection schemes for substation equipment (busbars, lines, transformers, capacitor banks, STATCOMs, and fixed series capacitors) and generating documentation packages including wiring schedules, label lists, cable schedules, bills of materials, and terminal block schedules.
Control Panel Design
Designing control panels for line, transformers, FACTS, and mimic system control desks.
Relay Integration & Parameter Settings
Calculating relay parameter settings, configuring logic equations (GOOSE, PSL), and loading profiles for numerical IEDs (Siemens, ABB, GE, Schneider, Hitachi).
Testing & Commissioning Support
Generating secondary injection testing parameters, FAT/SAT checking checklists, and providing on-site engineering supervision during commissioning.
SCADA & Substation Automation Systems (SAS)
A Substation Automation System (SAS) automates monitoring, control, protection, and alarm functions within electrical substations. Traditional substations relied on miles of copper hardwiring between switchyard equipment and control room relays.
IEC 61850 transformed SAS architecture by replacing heavy copper hardwiring with high-speed Ethernet communications and standardized data modeling (SCL, SCD, ICD, CID files).
Substation Automation Systems (SAS)
Designing Station and Process Bus networks, single line diagrams (SLD), mapping logical nodes, and configuring IED configuration files.
SCADA Systems Integration
Database mapping, HMI screen layout configuration, alarm routing matrices, sequence of events (SOE) lists, and master station communications integration.
Remote Monitoring Solutions
Setting up remote gateway access, cybersecurity firewalls, engineering workstation access networks, and IoT sensor monitoring for plant parameters.
Protocol Conversions & Gateways
Interfacing legacy RTUs and multi-vendor networks via standard gateways, supporting conversions across Modbus, DNP3, IEC 60870-5-101/103/104, and IEC 61850.
Substation Modernization & Numerical Relay Retrofits
Older substations face high maintenance overheads, obsolete spare parts, and lack of grid data interfaces. We specialize in brownfield upgrading, replacing electromechanical relays and wiring systems with modern numerical systems with zero structural rebuilding.
Legacy System Upgrades
Audit and analysis of existing panel schematics. Designing boundary interfaces, intermediate terminal link blocks, and relay adapters.
Relay Replacement
Extracting configurations from static/induction devices and migrating functions to multi-functional numerical Intelligent Electronic Devices (IEDs).
Control System Upgrades
Replacing conventional mimic control desks with space-saving HMI consoles, integration of network gateways, and digital alarm systems.
Outage Engineering
Scheduling transition programs and cutover wire lists to permit step-by-step panel replacement within short, scheduled utility outages.
Advanced Grid Solutions & FACTS Technology
As the electrical grid incorporates renewable wind, solar, and high-frequency power electronics, maintaining power quality and voltage stability becomes critical. We design logic controls and interface systems for advanced grid stabilizing installations.
FACTS Integration
Designing logic integration, sequence control diagrams, and protection schemes for Static Var Compensators (SVC) and STATCOM plants.
Auxiliary Panels
Engineering AC/DC distribution boards, battery charger monitoring systems, and auto-transfer switch (ATS) logic controllers.
Power Quality Systems
Integrating transient fault recorders (TFR), power quality meters, phase measurement units (PMUs), and wide-area monitoring systems (WAMS).
Engineering Design & CAD to MicroStation Conversion
Our document vault is managed by drafting specialists using premium software suites. We produce clear, error-free documentation that serves as the blueprint for manufacturing panels and executing site wiring.
CAD Drafting & Drawings
Developing Single Line Diagrams (SLD), schematic drawings, terminal plans, structural layout coordinates, and interpanel wiring lists.
CAD to MicroStation Conversion
Translating AutoCAD files to Bentley MicroStation (DGN) format, maintaining strict utility cell libraries, line weight tokens, and level standards.
As-Built Documentation
Updating drawing sheets post-commissioning based on field redline markups to maintain exact operational records.
Engineering Management
Version control, revision management (using ISO 9001 checklists), drawing package review, and digital vault management systems.
